Speaker cones can be damaged in many ways. Often they are bumped by people or furniture while being moved and this leads to tears or cracks in the cone. Some cracks develop simply because the speaker is old and brittle.
Repairing your own speaker cones can save money. The cone is made from stiff paper or light cardboard, so it is easily fixed with items that you can find around the home. Unscrew and take the woofer out of the speaker box. Disconnect the wires and measure the tear or crack. Cut out a piece of the construction paper to fit over the crack.
Use a color of paper that is similar to the cone color to make the repair appear seamless. Try not to make the patch much bigger than the crack as a larger patch can compromise the integrity of the cone as well as affect the sound. Using the small paintbrush, dab a small amount of the adhesive onto the tear edges and place the paper patch on top of it.
Hold in place for two minutes. Paint a thin coat of the rubber cement around the edges of the paper and allow it to dry.
Make sure you cover the whole tear so there are no gaps. Turn the woofer over and paint a coat of adhesive over the backside inside of the crack. Allow this to completely dry before testing the speaker with sound. If the crack is thin and small, you can just stick the edges together with the rubber cement, without using a patch.
This is a temporary job because a cracked woofer is probably old and will develop more cracks over time. A crack or tear means that the integrity of the cone is impaired and air will not move around it as designed. If you continue to use a cracked speaker, the crack will get bigger and the surrounding card more stressed.Login or Sign Up.

A mic stand fell over and hit the cone, at first it looked fine, there was no dent or visible marring of any kind.
Then after closer inspection I found out that the cone split very cleanly. The split doesn't go all the way up or down, it stops before the surround and before the dust cap but its most of the length of the cone. Can this be repaired? Could I just put a bit of superglue along the crack and call it good? Will the weight of the super glue throw the thing out of whack?
Tags: None. Re: Poly cone repair? Comment Post Cancel. I've not had to repair a split poly.
But I'd try "SG" first. The weight will be insignificant. Didn't figure a gram or so added to one side of a 12" cone would be significant.
Then again I'm sometimes wrong about things, so I figured I'd try to tap into someone's first hand experience. I'm guessing the SG fix would be almost unmeasurable.
Originally posted by Sydney View Post. Hrm, I figured superglue would work because it tends to have a melting effect on plastic and would hopefully fuse the cone pieces back together. I could also try something else like epoxy or fiberglass resin. But I also hate to throw away stuff for no reason, I was thinking of eventually trying to use them as the bottom of a made out of junk I had laying around 3 way.
I guess whatever I end up doing I'll post results for future generations. It is the duct tape of glues. All rights reserved.
Yes No. OK Cancel.When this happens, the drive unit can buzz or crackle when sounds are being reproduced. It is a most unpleasant sound. The buzz or grating sound is caused by the small fragments of cone around the hole vibrating.
A further issue is that if the speaker is used with an enclosure, the hole will cause loss of pressure and cause the backward wave to emanate from the front causing cancellation.
Speaker Repair Kits
This will change the sound from the overall speaker system. When this happens the speaker needs replacing or repairing.
Sometimes it can be possible to obtain and fit replacement cones. If no other method is available one last ditch method to save and repair the loudspeaker that has worked well in the past uses a small patch.
Most speaker cones are made of paper, and so a repair using some tissue paper works well. It may also be suitable for other materials, but assess the break and material to find a suitable alternative if necessary. Take the tissue paper and cut it so that it covers the hole, with a small overlap around the hole.
The tissue paper is sufficiently light that it should not affect the operation of the speaker unduly. It may be worth testing the tissue paper and the glue together first to make sure that the tissue paper does not shrink - this could distort the cone.
This tissue paper can be glued to patch the hole. Make sure all the tissue paper has glue and that there are no lose edges otherwise these could create a buzz.
If possible repeat the process on the under-side of the cone if it is accessible so that the repair is secured from both sides.
Use a flexible glue and then the rigidity of the cone will not be affected too much. Also use the minimum glue consistent with creating a firm bond, otherwise the mass of the cone will be altered and its performance changed.How to Repair Speaker at Home

The only problem was that the speaker cones were badly cracked from the previous owner pushing to many watts through them. I bought them, took them home, and discovered a cool trick to fixing the cracks which you are about to learn about. Don't blame me if you break your broken speaker cones lol. This wont properly work on metal or plastic cones.
This fix will likely not make your speakers sound better than they did before they cracked. It should however sound better than they did when they were cracked. Here is what you will need to fix your speaker.
Elmer's glue, gorilla glue this stuff also works great for fixing cracks in speaker dust coversor another type of semi flexible wood glue A regular coffee filter. A paint brush. I recommend a semi stiff bristled brush as it helps to rub the glue into the speaker cone Scissors A plate and last but not least a broken speaker Your first step is to water down the glue so it will properly soak into the speaker cone. Mix the glue with one part water to three parts glue. I wouldn't recommend adding any more water as it could cause the glue not to stick or make the speaker cone all soggy.
Start by filling in the crack with glue and letting it dry. Depending on how badly cracked your cone is it might take several applications.
Remember to get both sides top and bottom of the cone filled with glue. Next take a piece of the coffee filter and cut it to size so that it covers about a quarter inch to a half inch on every side of the crack. Try and tear the coffee paper whenever possible instead of cutting it. This helps the fiber bond to the cone better and prevent the edges of the patch from peeling up over time.
Apply a relatively liberal amount of glue to the top and bottom of the patch patch as well as the cone it's self. Once your done it may be a good idea to go back around and put some more glue around the edges of the patch to keep it stuck down. You can now let the glue dry. Genially you sould only need one layer of the coffee filter patch but in high wattage applications like large subs I recommend adding a second layer of the patch for safety.
The final step is to paint the patch. This is pretty straight forward. That wasn't so hard now go try it your self if you haven't already. Leave a comment or question below about how it goes. Question 6 months ago. Question 1 year ago on Introduction. Thank you so much for this. One of our Mission speakers started buzzing and vibrating, especially on bass lines. It ruined all our music and my husband was looking at getting new speakers.Back To Table Of ContentsJust before April 2012, after years of Google doing little to combat this type of off-page SEO at scale, even an inexperienced link builder could make just about anything rank in Google, for anything, without much consequence.
Simply by creating a 300-word article and building 500 unnatural links to it from (even very low-quality blogs) with unique anchor text, spread out over a few months, you could achieve top rankings.
It can still be effective, but this activity comes with an increased risk of Google penalty, even when you are an experienced black-hat. Google has a few surprises for Webmasters bending the rules using what they call spammy links. My blog is not a black hat SEO blog. I work with companies who are thinking of the long-term health of their business and who understands that the key to ranking in Google in the future is by making the website better, richer in content and the best user experience it can be.
Too many people submit spam reports and too many people engage in negative SEO for me to invest too much in unnatural links these days. If you want to rank in Google with any confidence in the long-term, you are going to have to INVEST in GOOD, IN-DEPTH content, and a few GREAT links. You can ALWAYS pick up the odd decent link to good content. This page is an example. I deleted some old posts on the Hobo blog, reworked some out of date advice, merged similar content.
I added some videos from Google, who now advise on the subject-matter where they once did not, and I created this in-depth page that, I hope, is of some use for beginners wishing to market a website successfully in Google in 2017. Some bloggers did notice, however. But before that, let us look at the big traders or the warren buffets of this world.
Interestingly, you can easily see which sites you are in competition with in the SERPs by looking for similar ranking keywords. Take for example Hobo-Web. Quality content drives the organic link building end-results Google claims it wants to reward with visibility in its SERPs. High-quality seo copywriting has never been so important. Google often still relies on links to find, index, categorise and rate websites (and pages) in 2017. Content will always be king (especially in the future) but without links, content can still be a moot point.
Links are like lasers. Links have the potential to make a site hot, and send that site to the top of the results. Some links get hotter in time, some get colder, and some disappear as each site is affected by those linking to it and from it. In the diagram below, you can see in any collection of pages, there is natural heat, naturally hot and cold sites, because of the natural interlinking going on between pages.
In this model, popular sites are hotter than unpopular sites, and this is a reflection of the real webHot sites are well known and well linked to and more likely to rank for any term if a page is properly optimised on-page and via the internal navigation structure of the website.
Hello, Google Supplemental Index. Or whatever Google calls it in 2017. Google hates paid links because it is an obvious way to generate heat signature, and ranking ability, a site might not deserve. One thing is for sure, though. If Google were confident they could via algorithmic calculation clearly identify paid links, the whole internet marketing industry would not have been talking about the war on paid links. The hotter a site, or rather page, the better the link for your site.
If a keyword is in the anchor text of the link, even better, but only if it is an EDITORIAL LINK, in 2017. The problem is, the easiest links to find out there are on pages with very cold, or at least very diluted heat signatures.
I prefer focusing on improving those signals above, rather than just manipulating link popularity. Google calls that spam, and will punish you for it if it detects an intent to deceive its algorithms.
Not that that stops a good spammer of course.
